SPECIFICATION forming part of Letters Patent No. 752,260, dated February 16, 1964i.

Application filed June 27, 1903. Serial No; 163,419 (No modeL) .To all whom it may concern;

Be it known that I, HIRAM EDWARD REED, a

citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl- Vania, have invented new and useful-Improvements in Vises,-of which the following is a specification.

This invention relates to vises; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and set forth in the claims.

"The invention is illustrated in the accompanyin'g drawings, as follows:

Figure 1 shows a section on the line 1 l in Figs. 2, 3, and i. Fig. 2 shows a plan view of the vise; Fig. 3, a section on the line 3 3 in Fig. 1; Fig. 4, a section on the line 4 4 in Fig. 1. r

A marks the base of the vise, from which extends a swivel-pesto. The vise-frame B has a swivel-socket t, which is-designed to operate on the post a, and thus permit the vise to be swung on the. swivel formed by the post a and swivel-socket 6. The upper end of the frame B is provided with a swivel-socket Z), the axis of which issubstantiaily horizontal. The shank cof the relatively fixed jaw G fits in the socket b and permits thervise-jaws to be swung on the horizontal axis. The ends of tion-surfaces 6 and b the frame forming the socket 6' form the fric- The shank (Z of the movable jaw D slides in the shank c of the fixed jaw. The screw E is provided with a shoulder e, which engages the movable jaw in the usual manner and operates through a nut F. The screw-shank is provided with the usual handle 6 and the shank d is reinforced by the sleeve or pipe D.

The nut F has the yoke f, which extends through slots (2 in the shank d of the movable jaw and is secured to a friction-ring f. The

friction-ring f is secured to' the shank c by the screws f These screws are not, however,

set-up sufiiciently tight to bring the frictionring f into close engagement with the frie tion-surface t. On the end ofithe screw E is arranged a cap 6 .This is secured to the end of the screw by the pin c. It engages the end of the shank d, its purpose being to 5 compel the movable jaw D to follow the screw as, the screw is run out, or, in other Words, to open the movable jaw. The yoke F, acting on'the sides of the slot at, holds the-jaw D in register with the jaw C. This is especiallyadvantageous when the shank d is round, as shown.

It will be noted that when the vi se is closed and pressure; exerted on the fixed jaw G and nut F the part of the frame forming the socket is clamped between the surface 0 and set sufiiciently tight to create enough friction to hold the parts in any position to which the jaws may be adjusted while the screw E is being operated. If desired, the jaws of the v I vise may be locked against turning on this horizontal pivot by means of the pin'f which is arranged in the friction-ring f and enters the socket 12*.

-I prefer that the locking of the swivel-joint formed on the post a should also be accomplished automatically by the setting of the screw E. To this end I have provided the upper end of the base with the groove c and have arranged the block G in the opening 6 in the wall of the socket b, so as to register with the post along the groove 0 The block G protrudes slightly beyond the surface 6 and is therefore subjected to the pressure of the clamping-ring when the jaws of the vise are set. This brings the inner 'end of the block Gr, which is in the form of a segment and adapted to fit in the groove a into close frictional engagement with the post a, so that the vise is thus automatically locked against swinging on the base a. The pressure exerted by the block upon the post is in the same direction as is the pressure exerted upon the block, or, iii-other words, there is no'bell-' crank action, the pressure from the clamping mechanism being directly communicated through the block to the post, pin 6 which is adapted to enter holes a in 1 provide a.

the post for positively locking the vise on this swivel, if desired.

What I claim as new is 1 In a vise, the combination with the frame having the socket Z) thereon with the frictionsurfaces 6 and b"; the vise-jaw having the relatively fixed shank c swiveled in the socket b; the friction-surface 0 thereon; the movable jaw D having a shank (2 operating in the shank .c, said shan'k 03 having the slot d therein; the

screw E arranged tooperate against the movable jaw; the nut F; the friction-ring f connected with the nut F through the slot '03 and arranged to operate against the surface 6 to exert pressure thereon and to clamp the shank c in the socket b as the vise-jaws are set.

2. In avise the combination with the swivelpost; a frame journaled on the swivel-post 7 having an opening adjacent to the. post; a

block arranged in said opening, said block being. subjected to the pressure exerted on the jaws; and exerting pressure upon the post vsaaeo exerts pressure upon the block, the movable aw; and a screw for operating it.

' 4. In a vise the combination with the swivelpost A having a groove (4 therein; the frame B swiveled thereon, said frame having an opening 5 thereon; the block G arranged in said opening, and having a curved surface to conform with the shape of the groove a; the fixed jaw and the nut of the vise, said jaw and nut being arranged to clamp the frame B and block G; the movable jaw; and a screw for operating it.

5. In a vise the combination of a swivel-post a; the frame B arranged to swivel thereon, having the swivel-socket b therein, frictionsurfaces 6 and b thereon and the opening I) thereon; the block G in the opening I), said block extending beyond the surface 6 a fixed jaw C having the shank c; a friction-surface c; the shank a being swiveled in the socket I); the surface 0 arranged to contact-with the surface 6 the movable jaw D having the shank d with the slot (5 therein; the screw E arranged against the movable jaw; the nut]? in which said screw operates; and the friction-ring f connected with said nut.

.In testimony whereof I have hereunto set my hand in the presence of two subscribing
